APPARATUS FOR CUTTING HUMAN HAIR OR CLIPPING ANIMALS.

SPECIFICATION forming part of Letters Patent N 0. 675,492, dated June 4, 1901. Application filed November 19, 1900. Serial No. 36,928. (No model.)

To (tZZ 10700712, it may concern:

Be it known that I, ALBERT MARTIN, horseclippermanufacturer, a subject of the Queen of Great Britain, residing at 229 B u rrage road, Plumstead, London, England, have invented certain new and useful Apparatus for Cutting Human Hair or Clipping Animals, of which the following is a specification.

According to this invention all the parts of the apparatus are held together by a single screw, about which the movable handle turns, the arrangement being such that by turning a nut on the screw the pressure between the cutter-plates is increased without tightening the movable handle.

Figure 1 is a plan of the clipper, the handles being broken away. Figs. 2 and 3 are sections on the lines 2 2 and 3 3, Fig. 1. Figs. 4 to 13 are detached views of the various parts. Fig. at is a plan of the lower cutter-plate (t. Fig. 5 is a plan of the upper cutter-plate Z). Fig. 6 is an under side view, and Fig. 7 an edge view, of the presser-plate c. Fig. Sisan edge view of lower handle (1, and Fig. 9 is a similar view of the upper or movable handle 6. Fig. 10 is a plan, Fig. 11 a side elevation, and Fig. 12 an end elevation, of the bridge-piece]? Fig. 13 is a side view of the screw g. Figs. 1t to 19 show a modification. Fig. 1% is asimilar view to Fig. 2. Fig. 15 is an under side view. Fig. 16 a plan, and Fig. 17 an edge view, of the lower handle 61 and presser-plate c, which are made in one piece. Fig. 18 is a plan, and Fig. 19 a side elevation, of the sleeve f and its prolongation f. Figs. 20 to 22 show the mannerin which a spring is applied to the handles. Fig. 20is an under side view of the clipper with the cutter-plates removed. Fig. 21 is aside elevation, and Fig. 22 an end elevation, of the nose of the movable handle.

In Figs. 1 to 13, a is the lower cutter-plate, having in it four holes a a a a his the upper cutter-plate, havingin it three elongated holes Z) I) c is the presser-plate, having on it two lugs c c, which pass through the holes I) and a thus serving as guide-blocks for the upper cutterplate. The presserplate also has a hole 0 through it. (Z is the lower handle, having on it a lug d, which fits into the hole ct in the cutter-plate a. The handle also has a hole d through it. e is the upper or movable handle, having on it a lug a, which works in the hole I) in the upper" cutter-plate. The handle 6 has a sleeve 6 made in one piece with it. The lower part of this sleeve fits into the hole 0 in the presser-plate. fis a bridge-piece bearing on the presser-plate c and bridging over without touching the handle 6. The bridgepiece is in the form of a sleeve f, provided with two legs f, bearing on the presser-plate. It has in it a recess f into which the upper part of the sleeve 8 fits, and a hole f through it. g is a screw which passes through the holes a and d sleeve 0 and hole f its upper end being provided with a nut 7t. On turning the nut the bridge-piecef forces the presser-plate c downward, so pressing the teeth of the cutter-plates a and b together. It will be observed that the presser-plate only takes a bearing in three places'namely,along the front edges of its two limbs on the plate F) and at its rearmost point on the handle (Z. This construction causes the teeth of the two cutter-plates to be very evenly pressed together. It will also be observed that turning the nut h does not force the handle 6 downward, a small amount of play being allowed between the top of the sleeve 6 and the bridge-piece.

The arrangement shown in Figs. 14 to 19 differs from that just described in that the presser-plate c is made in one with the handle d. The legs f of the sleeve f, which bear on the presser-plate are replaced by a tubular prolongation f, which screws into the hole 0 in the presser-plate c. The sleeve f may in this case be in contact with the handle e, and the friction between the handle and the presser-plate may be regulated by turning the sleeve. This friction in this case also is not altered by turning the nut 7t, whereby the pressure between the cutter-plates a and b is regulated. In other respects the arrangement is similar to that first described. The two modifications embodied in this arrangement are independent of each other and can be adopted separately.

Figs. 20 to 22 show the manner in which a spring may be applied to these clippers to enable them to be used with one hand. The handle 6 is provided with a prolongation or crank 6 and the handle (5 has a hole or tube bored in it. In this tube is a helical spring 70, having one end bearing against a flange at the inner end of the tube and its other end against the nut l, which screws onto the connecting-rod m, hooked onto a crank-pin e on the crank e The spring 70 is of sufficient diameter to allow the rod to oscillate about the nut as a hinge. By turningthe nut Z the compression of the spring 7c can be adjusted. It will be observed that the crank e and rod m are at an acute angle to each other, and this angle becomes more and more acute as the handles approach each other, the result being to equalize the effect of the spring, for as the compression of the spring becomes more and more its leverage becomes less and less.
